species are very pretty when in flower. A sandy loam 

 suits them best. Increased by offsets. 



S. cnprea (coppery). Jl., perianth tube purple; segments of a 

 yellowish-copper colour, purple at base and with a pale yellow 

 spot on each side ; spathe t wo-valved, jagged a little at the point ; 

 scape smooth, somewhat flexuons, two to four-flowered. June. 

 1. distichous, acute, mucronate ; lower ones smallest. Stem 

 about 9in. high, producing two or three scapes. 1825. (P. M. B. 

 L8;S. B. F.G. ser. ii.122.) 



S. elegans (elegant).* Jt., perianth pure white, slightly tinged 

 with blush, with a bright purple centre, above which is a broken, 

 black, velvety circle, marked with large, bright yellow spots ; tube 

 purple, shorter than the spathe, which is streaked with irregular, 

 broken lines ; scapes two or three, one or two-flowered. Spring. 

 i. distichous, bluntisb, with a very short mucro. narrowing as if 

 cut a little above the mi'ldle. Stem about 9in. high. 1827.

annuals. Seeds should be sown in the open border, late 

 in spring; or the seedlings may be reared on a gentle 

 hotbed, and afterwards planted oat. 



S. hyacinthoides (Hyacinth-like). JL deep bluish-purple ; sepals 

 lanceolate, acuminate ; petals spathulate-hnear, the limb reflexed. 

 September. I. sessile, narrow below, but clasping, oblong-linear, 

 acuminate. Stem simple or branching, 2ft to 3ft. high. 1834. 

 (B. M. 3516.) 



S. maculatns (spotted).* Jl. very showy, in simple or panicled 

 racemes; calyx purplish; petals deep velvety-purple in the 

 middle, lighter towards the crenulate edge; pedicels Sin. to 4in. 

 long, spreading. August /. ovate-oblong, 3in. to 6in. long, 

 glaucous, rather acute ; cauline ones clasping by long and obtuse 

 lobes. Stem lift, or more high. 1833. (B. M. 3317, under name 

 of S. oWim/oKum.)

STREFTANTHUS (from rtreptos, twisted, and 

 anthos, a flower; alluding to the twisted claws of the 

 petals in some species). ORD. Cruciferce. A genus com- 

 prising, according to Asa Gray, about thirteen species 

 of hardy, glabrous, annual or perennial herbs, natives of 

 mostly Western North America. Flowers purple, rarely 

 white or yellow, ebracteate, rarely bracteate, sometimes 

 pendulous ; two or all of the sepals saccate at base, often 

 coloured, sometimes very broad ; petals unguiculate, the 

 claw straight or twisted. Leaves entire, or the lower 

 ones Ivrate-pinnatifid ; cauline ones sessile or amplexi- 

 caul. Two species have been introduced ; both are 



STREPTOCARPTJS (from streptos, twisted, and 

 karpos, a fruit ; the capsule is spirally twisted). Cape 

 Primrose. ORD. Gesneracece. A genus comprising about 

 a dozen species of pretty, stove or greenhouse, often 

 villous or woolly herbs, sometimes stemless with spread- 

 ing radical leaves, or rarely caulescent with opposite leaves 

 (in some of the species, there is only one leaf in the adult 

 state ; this being, in reality, one of the cotyledons, which 

 has developed to an enormous extent) ; they are natives 

 of South and tropical Africa and Madagascar. Flowers 

 pale, purplish, blue, or reddish, showy ; calyx five-parted ; 

 corolla tube straight, declined, or incurved; limb ob-
